Schneider ATV930D22N4 Variable Frequency Drive (VFD)

1. Product Overview

The ATV930D22N4 belongs to Schneider Altivar Process ATV930 series, a high‑performance wall‑mount variable frequency drive for 3‑phase asynchronous and synchronous motors. It precisely regulates motor speed & torque for heavy‑duty industrial process equipment. This unit supports flexible IP upgrade from IP20 up to IP54 protection grade, embedded braking chopper, rich fieldbus communication, built‑in energy metering and asset predictive diagnosis. It connects with PLC / DCS systems to realize centralized factory automation control, widely used for energy‑saving speed‑variation and process protection of pumps, fans, compressors and heavy‑load machinery.
